Abstract (en)
[origin: WO2019110194A1] The invention relates to a method and a measuring system (100) for monitoring an extruder (10) or an injection molding machine during operation, comprising a measuring device (120) which is designed to generate a radar wave signal and to emit same in the extruder (10) or the injection molding machine and to detect a response signal corresponding to the emitted radar wave signal; and an analysis device (140) which is designed to ascertain a propagation time Δt, phase shift ΔΦ, and/or change in intensity ΔΙ of the radar wave signal on the basis of the detected response signal and to ascertain at least one operating parameter of the extruder (10) or the injection molding machine on the basis of the ascertained propagation time Δt, phase shift ΔΦ, and/or change in intensity ΔΙ of the radar wave signal. The operating parameter indicates the wear state of the extruder (10) or the injection molding machine and/or the phase state and/or the material composition of a material which is received in the extruder (10) or in the injection molding machine and which is to be processed.
